N-Trifluoromethylthio sulfoximines are biologically interesting compounds, but their potential is still poorly understood. The oxidation of N-trifluoromethylthio sulfoximines led to their corresponding sulfoxide derivatives as a new class of compounds, when using sodium hypochlorite pentahydrate (Na ...

The oxidation of various structurally different N-trifluoromethylthio sulfoximines was investigated using different oxidizing agents and conditions. Mono- and disubstituted phenyl methyl and phenyl cyclopropyl N-trifluoromethylthio sulfoximines were oxidized with NaOCl·5H$_2$O in water, while steric ...

Advances in understanding the mechanisms of homogeneous nickel catalysis has led to a remarkable progress in this field. However, the discovery of active catalysts is still largely based on trial and error, and the catalysts are mostly based on chelating (nitrogen) ligands. We report a combined theo ...

Arylidene-∆$^2$-pyrrolin-4-ones undergo organocatalyzed double spirocyclization with 3-isothiocianato oxindoles in a domino 1,4/1,2-addition sequence. The products contain three contiguous stereocenters (ee up to 98%, dr up to 99:1, 12 examples). The absolute configuration of the major diastereomer ...
